To nil whom it muy; concern w Re it known that l'. NATHAN V. linnniucas, a citizen of the llliiited States, res1din;r at lvl'ei'idian. in the county of Lauder-- dale and State of liflississippi, have invented new and useful improvements in Oil-Dus# tributing Apparatus, of which the following is a specification.

This invention relates to an oil distributinfr apparatus designed particularly, 'for use in surface coatingr roads and streets with dust-laying,T oils or tar products of the kinds commonly employed.

(lne object of the invention is to provide an oil distributing apparatus by means of which oil or tar ol anyY specific gravity or density may be distributed. and heavy grade oils distributed with greater eliiciency than is poesilile with distributers of ordinary construction. v

A tui-ther object ot the invention is to provide an' oil distributing apparatus Where- 'in provision is niade for distributing the oil or tar under air pressure in a regular'and even manner accordingr to the character of' the road and tothe speed ot' travel of the A still further object of the invention is to provide an oil distributing apparatus wherein provision is made/tor heating the air so as to maintain the oil or tar at the desired degree ot fluidity so as to insure its proper and even distribution and obviate any liability of the oil or tar clogging;r the apparatus at any time.

A further object of thev invention is to provide `an oil distributingz-ag'iparatus embodying: a means for supplyii'ig` the air at proper periods and pressure, to' provide novel'oil and air nozzles for spreading .the

oil and which are relatively adjustable to .govern the spreading action, and to provide means whereby the feed of the oil and 4the air may he manually as well as {internati-j cally controlled.

A still further object of'the invention' is to provide novel ineans tor removing the dust 'troni the road and depositing; itupon` the oiled surface. thereby insuring the direct deposit ot the oil and its cohesion to the surface, the laying or retention of all the trihuting nozzles.

particles. of dust, as well as the retention of the oil so that it will uniformly coat the road or street surface.

A still further object of the invention is to provide other improved tentures of construction, and to generally simplifynnd irn prove the construction and increase the etliciency oi apparatus of this character, as hereinafter fully described and claimed.

The invention consists of the features of construction, combination and arrangement ot' parts herein fully described and blaimed, reference being had to the accompanying drawings in which Figure l is a rear elevation of an oil distion. Fig. is a side elevation of the same.

Fig. 3 is a topA plan view of the apparatus.

Fig. 1l is a detail view of one of the cut-olf valves and distributing pipes connected therewith. Fig. l2 is an venlarged detail view, ypartly in section, of the air heater. Fig. '13 is n perspective viewof the dust removing and depositing device. Fig. 14 is a vertical transverse section through the suction 'fan casingr and' discharge nozzle4 l1 ,ateneo shaft 44 receiving' motion through chain and sprocket gearing vfrom one ot the axles 3 when the apparatus is in motion, so that the volume and pressure of the air supply will be governed by the rate of speed of travel ot the apparatus over the road or surface, to vary the supply of oil as such conditions require. This is unimportant part of the invention, as it is essential to a proper covering ot' the road surface with oil or tar that a` certain amount of oil' or tar must be distributed per square yard of the road surface, which can only be-elected by the use o't automatic means governed by the rate of travel or speed of the apparatus to supply theoil or tar in proper volume to the road surrace.'

lflach distributor 22 is of novel construction and comprises a` substantially -hatchetblade shaped oil discharge nozzle 46, coinposed of counterpart sections 47 united at their marginal side, edges by bolts or rivets v or equivalent fastening means 48, and having the lower arcuately curved rim 'edges thereofg formed to provide one or more slots or apertures 49 through which the oil outer is spread on to the road or street sui-tace. This nozzle is connected by a coupling member or collar fili-with the lower branch of a vertically disposed T-conneetion 5i., the latveral orhorizontal branch 52 ot which is concer-tml vby a coupling 5? with the coactingI oil t'eed pipe i3, whereby the oil supplied to the nozzle. Arranged within the nozzle -lii is an air discharge nozzle 5l, which is shaped to conform thereto1 but is spared at all sides therefrom to provide an intervening channel for the iiow oi the oil to be spread. 'l`his air discharge nozzle is ol a construction corresponding to the oil discharge nozzle andV isv formed with a discharge outlet arranged in proximity to the outlet or outlets i9, so that the blast ot' air issuing1 from the air discharge nozzle will jet or spread the oil or tar with the desired force and fincness against the surface to be coated.

rlhe air discharge nozzle is provided with lugs or Vprojections 55 which engage guide members 5G within the oil discharge nozzle and hold said air discharge nozzle centeredv within and with respect to the oil discharge' nozzle, and also provide for the proper guidance of said air discharge nozzle in its 'adjustments so that its discharge end 55- nnay be disposed closer to or l'arther from the discharge end Alll of the oil discharge nozzle for a regulation of the, action oi" the blast and discharge ol' the oil or tar to a nicety of degree to secure an even distribution ot the fluid. The inlet end ot' the nozzle 5e; communicates with a conducting' tube 57 which is in threaded engagement with an adjusting collar or sleeve 58 h aving a threaded engagement with the upper branch 59 ot' the T-connection 51, so that the air die charge nozzle may be adjusted as described, the upper end ot the tube 5? heing;1 connected with the coperating feed pipe or tube. '21. lt Will thus be seen that when the apparatus is in operation the main controlling valve 42 will be opened to a greater or less degree through the action of the governor according to the travel of theapparatus, and will therefore supply air to the pressure charm bers of the valves llito open said valves for the feed of regulated quantities of oil or tarte the discharge nozzles, the air thence discharging through the outlets 34 and keeping the valve casing thoroughly heated to maintain the oil or tar in a freely liquid condition so that it will not clog or interfere with theinovements of the valve.

7When the motion of the apparatus stops, the governor will automatically close the main valve 42, which will result in the automatic closure of the valves l2 through the action of their closing springs 31, thus insuring the positive cut-ofi" of the feed of i oil, similarly the main valve 42 and valve members 24 will he opened to varying degrees accordiner to the speed oiE travel of the apparatus to proportionately regulate the feed of oilv or tar to the discharge nozzles, so as to insure a perfect distribution of the fluid and coatinpy of the road or street surface, while at the same time preventing waste of. the material. ily also combining with the oil or tar at the points ot discharge heated air in the t'orm oi a blast through thc air discl'iarge nozzles, the nozzles will be prevented from clogging or choking' and the tiuid kept in a properly heated condition ior aomization to. the degree necessary to insure a perfect spread. This system of distribution. wherein the oil or tar is disehurt'ed in, the manner described7 provides lor the eliicient use ol' heavy viscous grades ot' oil and tar in a most eliicient manner, since the. oil or tar may be laept in an absolutely fluid condition at all times. with manitest advantagesA tlhilline ot the oil or tar may thus be prevented while the distributing mechanism is bein;F connected with a new storage supply tank.` after theone in Ilse has become exhausted, during' which period the flow ot' the oil is arrested in the distributing mechanism and the oil is liable to become viscous and clot,r up the valves and pipes.

lt will, ofcourse, be understood that any suitable or desired number ot' distributors roo or discharge nozzlesrn'iay be employed and that these may be sin'iported with the feeds Ylight oils, the heating elements need not be used or may be dispensed with. lit 'will be apparent that as, with the described structure, the feed of the oil to the nozzle is not only automatically controlled according to the speed or" the apparatus, but that the sup ply of air and oil to the individual nozzles may be individually governed, the nozzles may be controlled to distribute the saine or variable amounts of oil according to the condition of the road or surface to be treated. On well traveled roads or highivays, the greatest Wear occurs mainly in the center of the road, Where it firstneeds repairs, or where it .i'irst wears out.

With the present construction, the valves may be adjusted at any time without stopping the machine to distribute a greater `or less amount to any one or more of the noz! zles, so that the supply of oil to thc road suriace may be graduated from light 'to heavy or heavy to light and applied in proper volume as the particular needs 'of the road require. The ou er or oil discharge nozzle, at least, of each nozzle device yis composed of sections .to admit of the ready application and removal of the air nozzle, as Well as to provide for the readlgyv cleaning or repairs of the nozzles when necessary. By the useof a main cut-oil' valve in conjunction with individual valves in the air and oil feed pipes, the feed of the oil as vvell as of the air may be controlled to an exact degree without stopping the apparatus, the adv-'antages'of which will be evident.

ln applying the oil tothe surface oi a roadway it is very importanh'in order to secure' the proper cohesion, 'that all particles of dust be removed. A direct blast of air on the road surface has the disadvantage ci a great portion of the dust settling back on to the road before the oil strikes it, and also when this dust is raised in the open much of it is blown into the. spray ot' oil and .the atoms of oil are to a. greater'or less extent coated with it and their adhesive qualities thus impaired. ln order to overcome this objection l provide means for removing the dust from the road surface by a suction, allowing the distributing nozzles to spread the oil on to the hard road surface, 'after which the'talren up dust is deposited in the form of a film` or layer over the oil. As shown,'the casing S of the suction fan 9 communicates with a suction nozzle 61, arranged to move over the surface of the road, for the purpose or" drawing up all free particles of i ust. This nozzle is disposed in advance 'of the oil distributers `and thus'acts to clean and leave the road substahtiall-y free from dust so' that the oil will be distributed upon the body or hard surface of' the road. ,This dust will be forced by the action of the fan rearwardly through. to pipe 62 and deposited through a nozzle 63 on to the oiled surace of the mienne ground. this means perfect adhesion be-l tween the road and oil or'tar is secured, while the deposited' layer of dust acts to hold the oil against draining of? from the'high portion or crest of the road, an even coating il e l tines or fingers,r while the .latter are adapted 3C to independently bend or Hex underlpressure from contact with the road surface, thus allowing the rim or mouth of the nozzle to conform to the contour of the road surface as well as to contorni to depressions land iifgVv regularities therein, obtaining an eliicient suction action fortlie taking up of the dust.

Under some conditions l may dispense. with the heater 18 and substitute in lieu thereof a tube or pipe 18 leading from the 90 air heater 1i to and through the header or chamber 11, and thence through the pipe 10, and extending outward through said pipe, so that the heated air from the heater 14 may4 pass through the oil feed connections 95 described and finally discharge into the atmosphere. Suitable valves 18h and 18 are provided in this pipe 18 for the purpose of controlling the tloiv of the heated air. BV

the use of this construction of heater the oil may be heated to such a degree as will prevent it 'from becoming still' when the machine is standing for-any length of time or l the oil becomes chilled and heavy in its How. When the oil is movingvivith sui'iicient 105 freedom, this heating device may be out out of operation, and may be dispensed with entirely in the use of light oils. In some cases, .it desired, the exhaust from the engine may he conducted through a pipe 18 into 11o the cylindrical casing 18, as shown ,in Fig. 18, and the latter may be made to surround the pipe l0 throughout its entire length, so that a heating jacket of high eiiicieucy will' be produced.
